Design files

Overview

PMP11065 is an isolated synchronous flyback converter with dual outputs of 3.3V/2.5A and 5V/2.8A.  The 36-60V input is suitable for use in most telecom and PoE applications that require high efficiency.

Features
  • Efficiency of 90% with 48V input and maximum loads
  • Good line/load regulation with optocoupler feedback
  • Dual outputs save space and cost
  • 1500Vrms isolation for telecom or PoE
